York Cold War Bunker
York Cold War Bunker
The most modern property in the care of English Heritage is a partly underground bunker constructed during the height of the Cold War as a military fallout shelter and command post in the event of nuclear war. The Bunker is officially known as Number 20 Group Royal Observer Corps HQ, and was in service for 30 years from 1961 until 1991.
The bunker was built to house 60 staff and was intended to act as an observation post for monitoring the effects of nuclear fallout in the Yorkshire area. The interior displays the original communication and monitoring equipment, plus special decontamination rooms and a peculiar sewage ejector system intended to help keep the bunker completely separated from the outside world.

A special guided tour helps interpret the bunker, and tells the harrowing tale of the days when Mutually Assured Destruction was considered a very real and imminent possibilitity.
